Capacity & kit layout

This RIMLANCE kit provides 8 GB of DDR4 memory in a matched pair of 4 GB modules. The dual-channel configuration lets a desktop board interleave data across both sticks for higher throughput. Unbuffered, non-ECC UDIMMs keep the design simple for standard consumer platforms.

Who this suits

Builders upgrading an older DDR4 system or assembling a budget office machine will find the CL19 2666 MT/s speed adequate for everyday multitasking. Users who need ECC error correction, registered modules, or higher frequencies for demanding workloads should look at other kits.

Deciding specification

The modules run at DDR4 2666 (PC4 21300) with a CAS latency of 19 at 1.2 V. If your motherboard and CPU officially support that data rate and timing, the kit will operate at its rated speed; otherwise it will fall back to the platform’s default JEDEC profile.

Questions about this item

How much heat and power will the 1.2 V DDR4 2666 kit add when the system runs all day?

The modules operate at 1.2 V, which is the standard low voltage for DDR4, so they generate modest heat and keep power draw low during continuous use.

What does my motherboard need to accept this 288-pin dual-channel kit?

A desktop board with two free DDR4 DIMM slots that support unbuffered non-ECC UDIMMs at 2666 MT/s will run the kit in dual-channel mode.

If I keep my existing DDR4 memory, will the CL19 timing of this kit force the whole array to run at CAS 19?

Yes, the memory controller will match the slowest CAS latency, so adding these CL19 sticks will set the shared timing to 19 for all populated slots.
